Filter by:Pediatric patients undergoing tonsillectomy and adenoidectomy usually have a high incidence of postoperative EA, which increases the risk of developing postoperative airway obstruction and respiratory depression due to anatomical characteristics of operative location and increased susceptibility to opioid analgesics. the study will compare between nebulized and intravenous bolus of dexmedetomidine as a prophylaxis against postanesthetic emergence agitation in children undergoing tonsillectomy, adenoidectomy or adeno-tonsillectomy procedures.
Postoperative delirium (POD) is a frequent postoperative complication in the elderly, characterised by fluctuating disturbances in attention, awareness, and cognition. Identifying the patients at highest risk of developing POD was the aim of the artificial intelligence (AI)-based algorithm PIPRA. This prospective cohort study is to externally validate the AI-based PIPRA algorithm. The primary endpoint is the performance (AUC) of the PIPRA algorithm in predicting POD. The secondary endpoint is the performance (AUC) of the clinicians in predicting POD (and how it compares with the performance of the PIPRA algorithm).
The main objective is to assess the 6-month prognosis of patients who presented with extreme agitation in the emergency room. The primary endpoint is the 6-month mortality of agitated patients.
This international, multicentre prospective cohort study will assess whether perioperative duration and magnitude of mean arterial pressure (MAP) outside of an individual's cerebral autoregulation (CA) limits using near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) are associated with adverse neurological events. It is to investigate whether patients with a higher burden of cerebral haemodynamic insults have an increased incidence or poorer neurological outcomes. Associations between neurologic outcomes, neurobiomarkers and genetic tests will be explored.
The objective of this study is to test the effects of caffeine on neurocognitive and clinical recovery after major surgery. Specifically, this trial tests the primary hypothesis that caffeine will reduce the incidence of postoperative delirium.
Thi investigators aims to observe the impact of perioperative body temperature and the noise of operating room on postoperative delirium for elderly patients undergoing abdominal surgery. And based on this study the investigators aimed to explore the potential risk factors of postoperative delirium for elderly patients undergoing abdominal surgery.
Remimazolam is an ultra-short acting benzodiazepine agonist which is used widely for general anesthesia and sedation. Remimazolam has several advantages. Remimazolam is rapidly metabolized by tissue esterase that it does not accumulate even after infusion for long periods of time. The presence of reversal agents (flumazenil) is also advantageous. Also, hemodynamic stability compared to propofol gives clinicians preference to use for geriatric anesthesia. However, the study on the effect of remimazolam compared to propofol on postoperative delirium have not been carried out. The purpose of the study is to compare the incidence of postoperative delirium and recovery profile in elderly patients undergoing orthopedic surgery using either remimazolam or propofol.
The study targets postoperative delirium in patients undergoing major abdominal surgery, with the aim to evaluate the functional baseline and proteomics implicated in pathogenesis, prevention strategies (such as anesthesia depth monitoring) and incidence in certain population groups.
Aortic valve stenosis is the heart valve disease with the highest prevalence among the elderly, and may lead to heart failure. Until recently, the only definitive treatment was surgical replacement (SAVR). However, the increased risk associated with the surgical procedure excluded patients with multiple co-morbidities. As the population is aging and more and more patients may present with aortic stenosis, the need of a less invasive approach has emerged. Transcatheter Aortic Valve Replacement (TAVR) offered an alternative therapy for these high risk patients. This new method has seen worldwide acceptance, has been proven very beneficial for these patients, and therefore its indications have been expanded to intermediate risk patients, as well. Until recently, general anesthesia was the primary anesthetic technique for TAVR, but conscious sedation or monitored anesthesia care (MAC) is gaining more and more popularity lately. Our knowledge regarding the comparison between general anesthesia and MAC in TAVR procedures is derived mainly from observational studies and few randomized trials. MAC seems to be associated with less inotropic drug usage, shorter procedural times, shorter intensive care unit (ICU) and hospital length of stay. However, according to published data, there were no differences in 30-day mortality and complications between these two techniques. Even less are known about the most suitable anesthetic agent for MAC during TAVR. Many drugs have been used, with propofol and dexmedetomidine being the most popular. However, there are only few comparative studies and their results are not conclusive. This study compares MAC under propofol and MAC under dexmedetomidine for TAVR in order to examine which method of conscious sedation comes with more beneficial postoperative outcomes for the patients.
To observe the effect of intraoperative dexmedetomidine on the incidence of postoperative delirium, postoperative analgesic drug requirements and pain scores in elderly patients undergoing major abdominal surgery.
